Income Taxes	Note 12—Income Taxes We are subject to tax liabilities imposed by multiple jurisdictions. We determine our best estimate of the annual effective tax rate at each interim period using expected annual pre-tax earnings, statutory tax rates, and available tax planning opportunities.

We recognize interest and penalties related to uncertain tax positions, if any, as an income tax expense. We do not include the income tax expense or benefit related to the net earnings or loss attributable to noncontrolling interest in our income tax expense as the entities are considered pass-through entities and, as such, the income tax expense or benefit is attributable to its owners. The effective tax rate on income including noncontrolling interests for the three months ended March 31, 2020 and 2019 was 29.0% and 21.3%, respectively.

For the first three months of 2020 and 2019, our tax rate differs from the U.S. federal statutory rate of 21.0% primarily due to the impact of state income taxes and nondeductible components of per diem expenses.

Note 12—Income Taxes

We are subject to tax liabilities imposed by multiple jurisdictions. We determine our best estimate of the annual effective tax rate at each interim period using expected annual pre-tax earnings, statutory tax rates, and available tax planning opportunities. Certain significant or unusual items are separately recognized in the quarter in which they occur

which can cause variability in the effective tax rate from quarter to quarter. We recognize interest and penalties related to uncertain tax positions, if any, as an income tax expense.

We do not include the income tax expense or benefit related to the net earnings or loss attributable to noncontrolling interest in our income tax expense as the entities are considered pass-through entities and, as such, the income tax expense or benefit is attributable to its owners.
